Abstract

Groundnut production in West Nusa Tenggara Province has increased every year. Post-harvest handling of peanuts at the farm level is generally still done traditionally, especially when harvesting, threshing pods or stripping the peel, which requires a lot of labour. This study aims to determine the effect of peanut pod diameter on each parameter, tool efficiency, and tool production quality. The method used in this research is the experimental method by conducting experiments directly in the laboratory. The parameters observed in this study are the efficiency of the tool, the need for electrical power, and the quality of peanut seed stripping. The analysis results showed that each treatment with different diameters had no significant effect on each parameter observed. The stripping quality of the three treatments has not met the standard.

Abstract

One of the materials that can be used to make activated charcoal is bidara wood. Bidara wood has a high carbon content and a good pore structure. In addition, bidara wood also contains several minerals such as calcium, potassium, and magnesium in small amounts. The content of these compounds and elements makes bidara wood very suitable to be used as a raw material for activated charcoal. One of the activation materials is an H3PO4 solution. In the activation process, bidara wood activated charcoal can improve its quality properties, such as surface area, pore volume, and adsorption capacity. Therefore, the aim of this research is to determine the effect of heating temperature variations on the quality properties of bidara wood activated charcoal using chemical activation with an H3PO4 solution. The experimental design used in this study is a Completely Randomized Design with one factor, which is the activation temperature (500, 600, and 700˚C). The results of the study showed that the use of H3PO4 solution at a temperature variation of 700˚C resulted in better properties for moisture content (5.41%), ash content (43.29%), and iodine adsorption capacity (4,737 mg/g) compared to the temperature variations of 500˚C and 600˚C.

Abstract

Low coffee production and quality are two major problems of the Indonesian economy that must be addressed, especially in smallholder plantations. The use of Growth Regulators (ZPT) and Planting Media in coffee with the grafting method is expected to help in the growth of coffee plants. This study was designed using a Factorial Completely Randomized Design (CRD) consisting of 2 factors, namely ZPT Growtone Concentration (G0: Control, G1: 20/250 ml, G2: 25g/250 ml, G3: 30g/250 ml) and Composition of Planting Media Soil, Manure, and Sand (M0: Control, M1: 1:1:1, M2: 1:2:1, M3: 1:3:1). Each treatment was repeated three times. The parameters analyzed included plant height, number of roots, root length, root weight, stem diameter, and number of leaves. All data obtained in the study are presented in the form of tables and diagrams. The data obtained will be analyzed using analysis of variance (ANOVA). To test the effect of treatment on the observed variables, if there is a significant difference, the DMRT (Duncan Multiple Range Test) further test will be conducted at the 95% confidence level. The results showed that the combination of ZPT Growtone and Planting Media types of soil, manure, and sand had a significant effect on the number of branches parameter, and each factor also had a significant effect on the root length parameter. The best treatment is the combination of  ZPT Growtone 20g/250 ml and Planting Media Composition 1:1:1. The treatment has the highest number of branches with an average of 2.67. The effect of the two factors on the grafting cuttings seedlings on the root length parameter was 16.83 and 16.96, respectively.

Abstract

Natural resources in Indonesia are very abundant, but there are still some that are not utilised properly so that they only become waste polluting the environment, one of which is acid wood. This waste can be innovated into briquettes. This study aims to identify the characteristics of briquettes from tamarind wood and coconut shells with starch adhesive, including moisture content, ash, volatile substances, bound carbon, and calorific value. This study uses a complete randomised design (CRD) as a tool to analyse significant data at the 0.05% level. Each concentration involves a variation of composition between tamarind wood charcoal and coconut shell charcoal, with additional starch adhesive in the ratio of 90%:10%, 45%:45%:10%, and 50%:40%:10%. Each sample will then be analysed for moisture content, ash content, volatile matter content, bound carbon content, and calorific value.  The results showed that the composition of the material mixture greatly affected the characteristics of the briquettes. The lowest average value of moisture content is at concentration P1 with a value of 1.69%, the lowest value in ash content is at concentration P1 with a value of 5.06%, the lowest volatile substance content is at concentration P1 with a value of 13.34%, the highest bound carbon is at concentration P3 with a value of 29.21% and the highest calorific value is at concentration P3 with a value of 6690 cal/gram. The characteristics that meet the SNI NO. 01/6235/2000 standards are only moisture content and calorific value, with the specified standards for moisture content <8% and calorific value >5,000. So from all five testing parameters of moisture content, ash content, volatile substance content, bound carbon content and calorific value, the best treatment was treatment P1 with 90% KA concentration: 10% adhesive.
